Other than that, it's totally simple. Just plug in the second card, attach xfire bridge (or two if you like) and fire up the rig, the driver will install for card 2 automatically. Then reboot and enable xfire if it doesn't happen automatically (which it usually does). A few seconds and screen flashes later, you're ready to rock.

So, I've been doing a lot of research on the board and I keep getting mixed answers. Since this is the newest post I've found covering xfire I'll post it here. Do I need one xfire cable or two? And why? OP how is your xfire 5770's working? Did you use one or two xfire cables? Thanks.

You only need 1. However people put 2 a lot but this is purely for looks.

I have my monitor connected to the bottom card , does it matter which card you have it connected too?My cards are running great by the way =)

Same here. I selected in Bios PCI-EX 2 as first Video. Call me old fashioned but I am doing anything possible to reduce temperature on the top card. I imagine that if I am giving video output through the second, I might reduce the stress on the first. The drawback? Everytime I flash the bios i need to go to card one, select again PCI-EX2 as first. Other than that, it works splendid.
